FIGURE-PUNCH FOR CHECKS OR OTHER PAPERS.

SPECIFICATION forming part of Letters Patent No. 521,358, dated June 12,1894.

Application filed May 18, 1888- To all whom it may concern:

Be it known that I, JAMES BAYARD BAOKUS, of the city, county, and Stateof New York, have invented a new and Improved Figure: Punch for Checksor other Papers, of which the following is a specification.

- inder.

Similar letters of reference indicate corresponding parts in all theviews.

My invention is in the nature of a hand punch for cutting figures inchecks and other papers, to prevent them from being raised or otherwisealtered.

It relates to that particular form of hand punch in which a revolvingcylinder is pro-- vided with a circular series of punchesand dies thatmay be successively brought into position between the jaws of saiddevice to bring into operation any one of said punches upon the check orother paper.

The particular object of my invention is to simplify and cheapen theconstruction of this form of hand punch, and to insure a more exact andcertain operation of the devices, and to these ends it consists in thepeculiar construction and arrangement of parts, which I will now proceedto more fully describe with reference to the drawings.

The levers A, B, forming the body of the punch, are pivotally connectedby a screw a, and the handles 1) 1) formed on the extremities of thelovers are pressed apart by a spring 0, secured to the handle I) andpressing against the inner surface of the handle b.

The lever A carries a frame D composed of two parallel rigid jawsbetween which is pivoted a cylinder E upon the pin 0, the said pivotalpin 0 being arranged at right-angles to the pivotal screw 0.. To thecylinder E is attached a disk F,"by the neck (1, so that the saidcylinder E and disk F will be made to turn together upon the pin 0.. a

The cylinder E is formed of three parts 6,

In the part g is formed aseries of equi- Serial No. 274,268- (No model.)

distant holes h, the number of holes corresponding to the number offigures or characters used in the instrument. In the part f are formedchambers t, which correspond in number and position with the holes h,and in the part c are formed holes j which are axially in line with theholes h and the chambers z'. The chambers i are somewhat larger indiameter than the holes h and j in the parts e and g for the purposehereinafter described. In the chambers 11 are placed the punches 7c, theupper ends of which project through the plate 9, and carry on the facethe figure or character to be cut from the paper. The lower end of suchpunch is provided with a head Z, between which and the plate 9 is placeda spiral spring on which keeps the punches normally ina depressedposition within the chambers. It is to accommodate this headland springm that the chamber 2' is made larger than the surface openings in thecylinder as above described. This constitutes an important feature of myinvention in simplifying and improving this class of punches, for suchsectional construction of the cylinder enables me to quickly bore thecylinder in a practical and easy way, to surely guide the punches, tosafely retain them in the cylinder against coming out, and toconveniently open the cylinder to inspect or remove the punches whennecessary.

In the disk F are cut dies n corresponding to the punches carried by thecylinder E, and between the dies n are formed openings 0 through whichthe checks may be viewed. In

the periphery of the disk F, opposite the centers of the dies n areformed V-shaped notches p.

Between the two jaws of the frame D adjacent to pivot on andsubstantially parallel with the axis-of the cylinder there is secured aspring g which projects through the frame and is provided with a knob0", for convenience in handling, and upon the said spring, within theframe D and opposite the edge of the disk F, is formed a V-shapedprojection s which is adapted to engage the notches p in the peripheryof the disk F.

In the lower part of the frame D is formed an opening 15, and an arm aof the lever B which projects over the frame D is provided with the studc, which is capable of passing through the hole t in the frame, and theopeningj in the part c of the cylinder E, and of pressing directly uponthe head Z of the punch k. The engagement of the V-shaped projections ofthe spring q with the notches p in the periphery of the disk F, causesthe holes j to register with the stud o and hole 25.

To lighten the construction of frame D and to give a suflicient range ofmovement to the arm u, the lower jaw of frame D is recessed at u on itsunder side to allow the arm a to enter and lie flush within the samewhen the handles of the punches are brought together. This externalrecessing of the lower jaw of frame D is extended upwardly to the otherjaw so as to receive the broad middle part of the handle arm, which isthus fulcrumed to the other handle arm externally to the frame, whichpermits of the easy assembling or disconnection of the parts, and readyinspection or adjustment, and at the same time preserves a compact andlight construction.

The paper to be punched is introduced between the cylinder E and thedisk F,as indi cated in dotted lines in Fig. 1. Then the handles 1) bare forced together, and the stud v is brought into engagement with thepunch 70, forcing it through the paper and into a die carried by thedisk F. For convenience in viewing the check, the extremity of the upperarm of the frame D is provided with a notch to which permits of lookingthrough the openings 0.

It will be observed that as the cylinder E and disk F are rigidlyconnected together, all the punches and their corresponding dies mustregister. The holes in the dies are cut through the disk F, so that thecuttings from the paper can readily drop out as the disk is revolved. Toprevent the punches from turning about their own axis they are eachprovided with a feather a which works in a slot in the part f. Theperiphery of the cylinder E is fluted to permit of readily turning thecylinder by the thumb of the hand in which the punch is held. TheV-shape of the notches p in the periphery of the disk F, and the form ofthe projection s on the spring q permit of turning the cylinder Ewithout the necessity of withdrawing the spring g by the thumb or fingereach time the cylinder is shifted.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A punch for checks and other papers, consisting of the combination oftwo arms pivoted to each other and constituting an operating handle, acylinder pivoted upon one of the arms and having a series of openingsand a series of punches carried in said openings, a disk moving withsaid cylinder against which said punches may be thrust, said disk andcylinder being separated to receive the paper to be punched, and asingle stud carried by the other arm for operating the punches, saidstud being rigidly fixed to and under the direct influence and controlof the handle arm and acting directly upon the said punchessubstantially as shown and described.

2. A punch for checks and other papers, consisting of the combination oftwo handle levers or arms, one having a frame D with parallel jaws, oneof which jaws and a portion of the frame being recessed externally, andthe other of which handle levers or arms is fulcrumed to the first namedlever externally within its recess, and carries at its opposite end arigid inwardly projecting stud, and a rotary cylinder or head pivotedbetween the jaws of the frame and bearing a spring q secured between thejaws of the frame in position substantially parallel to the axis of thecylinder, and having a projection adapted to enter the notches of thedisk, the said spring being also extended through the frame D andprovided with a thumb piece '1" substantiallyas and for thepurposedescribed.
